The Mineral Collection of the Department include a study collection of minerals and rocks for use by advanced undergraduate and graduate students. Some specimens and suites of minerals, crystals, rocks, and ores are on exhibit in hall cases in the C.C. Little Building.
The collection consists of ~15,000 mineral specimens including a superb suite of specimens from Michigan's copper mines, thousands of gemstones, several hundred meteorite specimens and a suite of rock samples from early expeditions to Antarctica.
Departmental Teaching Collections Many courses in Earth and Environmental Sciences involve "hands-on" science. The Department oversees a large collection of minerals, rocks, and fossils used specifically for teaching. This library of specimens allows students to build familiarity with materials they might see during field courses or in their own back yard.
This teaching and research facility includes a video-based image analysis system for acquisition and analysis of 2D morphometric data (coordinate values, distances, outlines, counts, shape indices, luminance profiles, etc.) at a full range of scales, and two devices for acquisition of 3D data, a Reflex microscope for work in the sub-decimeter range, and a mechanical-arm digitizer for work on larger specimens.

The Noble Gas Laboratory (NGL) at the University of Michigan is currently dedicated to analyzing all stable noble gas (He, Ne, Ar, Kr, Xe) abundances and their respective isotopic ratios in a variety of fluids, including freshwater (groundwater, surface water, rainwater), ice, snow, brines, shale gas, and gas from hydrothermal systems.
The laboratory is equipped with two Thermo Scientific mass spectrometers recently acquired and funded by the National Science Foundation (EAR/IF #1049822); a Helix SFT for measurement of He and Ne isotopes, and an Argus VI for measurement of Ar, Kr and Xe. The laboratory is also equipped with a noble gas extraction and purification line. The latter includes a double-head cryotrap which allows for simultaneous separation of He and Ne in a “low-temperature” chamber while Ar, Kr and Xe are separated in the “high-temperature” chamber. Measurements of a fluid sample are carried out simultaneously on the Helix SFT and the Argus VI. The Helix SFT is specifically designed to analyze 3He and 4He in multi-collection mode. Multi-collection in the Argus VI is also used for measurement of Ar, Kr and Xe isotopes.
Once the gases have been extracted from a sample, all clean up and cryogenic separation procedures are handled by a fully automatic computer controlled system. The computer that controls the gas extraction bench acts as a master computer, as it not only controls the extraction bench but it also commands the two mass spectrometers via an internal ethernet network. The entire system is coordinated by multi-threaded control software that allows for gas processing and data collection on two separate mass spectrometers simultaneously.
In the near future, the NGL will be also equipped with extraction and purification lines for measurement of all noble gases in rocks. These are currently under construction.
This laboratory complex includes a multi-use sample preparation and analysis facility. Instrumentation includes: GS/MS systems for analysis of the organic fraction of sediments and rocks, a Carlo-Erba CHNS-O analyzer and a Coulter Multisizer for precise grain size analysis.

The Museum of Paleontology provides the facilities enabling direct hands-on study of plants and animals preserved as fossils, and study of the environmental, ecological, and paleogeographical conditions in which they lived. These can be studied statically at fixed times in the past or present, and dynamically as they are seen to change through evolutionary and geological time. Because of the Museum and what it facilitates in terms of hands-on experience, our teaching and research programs have long been known for their empirical focus, with an emphasis on testing new ideas as well as generating them.
The Museum is located in the Ruthven Natural History Museum building at 1109 Geddes Avenue, across the street from the C.C. Little Building where the Department of Earth and Environmental Sciences is located.
In this laboratory we use realistic numerical models, idealized numerical models, analysis of in-situ and remotely sensed observations, and model/data comparison to better understand the dynamics and energy budgets of wind-driven and tidal motions in the ocean. Our research is interdisciplinary, often involving collaborations with marine geophysicists, geodynamicists, and glaciologists, as well as with other physical oceanographers.
